Abstract

The volume of mobile sediment on the river bed is the primary control on the dimensions of the bed forms that develop. If an unlimited supply of sediment is available the bed form dimensions which develop are determined by the water depth, the flow velocity and the sediment characteristics. This relation is described by the various models for the prediction of bed form dimensions which have been formulated (e.g. Van Rijn, 1984, Zhang, 1999). When the volume of mobile sediment is smaller than the volume required for equilibrium dimensions, the bed forms are supply limited and will remain smaller.
